I have recently started taking my nearly 5 month old ds swimming and I've realised it has made a dramatic improvement to his sleeping. He has gone from waking every 2 hours to a block of 5 hours sleep last night after swimming yesterday. Would it be too much to take him swimming 3 times a week? Also should i be putting him in the showers afterwards to wash the chlorine off? I havent done so far as I've just been wrapping him in a towel the minute he comes out of the water. Any help gratefully recieved for this clueless first time mum!
